An application has been filed in Germany April 14, 1932. This inventionrelates to improvements in handle fastenings of tools of all kinds,particularly 5 hatchets, axes and hammers, although it can be used inconnection with household tools or those for agricultural or industrialuses.

It is an object of this invention to provide a tool handle which willmaintain the handle and head of the tool against accidentaldisassociation and it is of a nature which will hold the head againstthe development of lost motion and loosemng.

It is another object of the invention to provide pensate for wear,shrinkage or other developments which might afiect the emciencyanddurability of the tool.

With the foregoing and other objects in view, the invention consists inthe details of construction, and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed. Y f

In describing the invention in detail, reference will be had to theaccompanying drawing forming part of this application, wherein likecharacters denote corresponding parts in the several views and in which-Figure 1 illustrates a view in elevation of a 3 0 hatchet with thehandle partly in section havin means for adjusting the means by whichthe head and handle are held'assembled;

Figure 2 illustrates a view on the line 1 2 oi Figure 1; V

Figure 3 illustrates a. perspective view 01 the head-engaging elementand a shaft or rod to which it is connected;

Figure 4 illustrates a sectional view 01' a iragment of the handle androd, showing a different 40 means of adjusting the same;

Figure 5 illustrates a view. in elevation of a hammer with a differentmeans for holding the hammer head on the handle, the handle being partlyin section; Flgurefi illustrates a sectional view on the line3-4ofFigure 5; and

Figure Tillustrates a perspective view of the head engaging member and arod associated therewith.

In this drawing a denotes ahatchethead, b

a handle applied thereto, the said handle having a. longitudinallyextending hole or channel a terminating in an enlarged recess a? atits'end. A rod e with a. threaded outer end extends through the channeland it has on its end opposite the means whereby adjustment may be madeto com- May 13, 1932,. Serial No. 613.3% Germany April 14, 1932 threadedend a plate 9 with flanges n and a that embrace the head of the tool. Anut ,f is threaded on the rod and a lock washer i on the rod engages thenut and holds it at different positions of adjustment. By means of thenut, lost motion may be corrected for it may he threaded to pull theplate g into engagement with the head and thus draw the head more firmlyon the handle. 7 Figure 4 embodies a. modification in which the nut f isthreaded on the rod and there is interposed between the nut and the endwall of the recess a; a spring k which-encircles the rod and by thismeans, the rod is always under the influence of the spring andoi coursean adjustment of the nut f can be made to increase the-iorce of thespring.

That term of the invention shown in Figure 5 includes a handled having achannel for the threaded rod e and a nut j is threaded on the rod sothat the pull on the rod may be adjusted.

' The member 0 may be in the nature of a hammer head, ax, orhatchetbladeor in fact any of the well known implements used in connectionwith. the industries to which reference has been made. A plate hisconnected to the rod e and it has resilient extensions, two of which, Iand m, are oppositely disposed and are intended to projectlongitudinally oi the head and to bear thereagainst on opposite sides ofthe eye of thehead. The plate is also provided with opposed trans--versely extending projections 12 and q which overlie-a. portion 01' thesides of the head and the relation of parts is-such that the distancebetween the lateral projections is less than the width of the head inorder that the said extensions which are integral with the plate andwhich are resilient in character bear against the sides of the head andprevent displacement of the plate. The extensions 1 and m are resilientalso and their resiliency is relied upon' to maintain the head undersuch pressure as-to prevent loosene'ss oi the joint between the head andhandle. The rod may be secured to the plate in any appropriate way, 1

but since this is not a material detail or construction, it is notdescribed with minuteness. I claim:

1. In a handle fastening for tools, a handle having a longitudinal hereon which the tool is mounted, a screw-threaded shaft arranged in thesaid longitudinalbore,

shaft, laterally embracing the head of the tool and yielda resilienthead on the said said head having tongue shaped portions and a memberthreaded on the shaft operative to exert a pull of the said head on thesaid tool.

2. In a handle fastening for tools, a handle having a longitudinal boreon which the tool is mounted, a screw-threaded. shaft'arranged in thesaid longitudinal bore, a resilient plate forming a head mounted on saidshaft externally of the tool and yieldably bearing thereagainst; thesaid WERNER PIEL.
